Spiral conveyor within the cylindrical housing with a continuous screw blade welded spring auger, rotating together with the helical blade chassis. Added materials due to the centrifugal force and friction force random shell rotation and lifted together custom rear spring auger, gravity material has slipped along the spiral spring auger supply side, so that the material along with the spiral rotation in order to achieve a material forward movement, does not rotate as the rotation of the nut screw along a translational movement, as the purpose of conveying the material. Screw conveyors and conveying formally divided into two kinds of shaftless screw conveyor screw conveyor shaft, in the shape into a U-shaped and tubular screw conveyor screw conveyor. Shaft screw conveyor is suitable for non-sticky powder materials and small particles of material (for example: cement, fly ash, lime, grain, etc.) without shaft screw conveyor for easy winding by viscous materials. Spring auger sales, Qijiang County spring auger, Ruifeng by Ning County Ruifeng machine parts processing department.
